Hello Steven,
No that file does not exist. I thought I could just link to my normal bzip2
or zlib library I built myself? I tried setting BOOST_ALL_NO_LIB to 1 so it
would not autolink, but now I get these errors on my zlib test program:

Any ideas how I can fix this?
Does the file libboost_bzip2-vc90-mt-gd-1_39.lib exist?
Have you set the library path in the IDE?
In Christ,
Steven Watanabe
